If I might channel my inner grumpy-old-man for a moment:
I find it curious that people who design nifty new devices are regularly referred to as "scientists". This is not science; it is engineering. Why not call it that?
Because the guys in this story are actually scientists, doing the discovery and research, as well as engineers .. and it is 'implied' that scientists can do engineering also, so I guess its Venn diagram time .. ?
I like what Cliff Stoll had to say about this... "The first time you do something it’s science. The second time it’s engineering. A third time it’s just being a technician" -- Ted Talks, 18 minutes with an agile mind.
